- ✓Thresholds and procedures should be checked in the current regulations of your own university or department.
- ✓The most important thing is to analyze specific fragments, sources and way of quoting.
- ✓You should not mechanically replace words just to lower your score.
What does the Uniform Anti-plagiarism System check?
JSA compares the text of the work with resources indicated in the system and detects similar strings of characters. The report helps the promoter find places that require assessment. He does not know the author's intentions and cannot independently decide whether a given similarity is a correct quote, a common phrase or an unauthorized borrowing.
Therefore, the quantitative result is the beginning of the audit, not its end. Two works with a similar percentage may be assessed differently: in one case they focus on correctly described quotations, in the other they cover long fragments without reference to the source.
Why isn't there one safe percentage?
Universities and departments adopt their own procedures for dealing with the report. They may define the values that trigger additional control, the method of re-examination and documenting the promoter's decisions. Current rules should be found in the diploma regulations or anti-plagiarism procedure of the relevant unit.
The specificity of the direction is also important. The legal work contains the names of the acts and the wording of the provisions, and the technical work may use fixed terminology. This does not exempt you from correctly labeling sources, but it shows why mechanical comparisons of mere percentages can be misleading.
How to analyze selected fragments?
First, you need to check the longest similarities and determine what source they come from. Then it is worth assessing whether the fragment is a quote, a paraphrase, an element of the bibliography, a proper name or a standard description of a method. Each category requires a different action.
The quote checks the quotation marks, footnote and page number. When paraphrasing, you need to assess whether the author actually presented the content in his own words and indicated the source, and not just changed a few words. In the bibliography and forms, attention is paid primarily to the correctness of notation and analysis settings.
Quotation, paraphrase and common knowledge
A literal quote should be clearly marked in accordance with the adopted style. A paraphrase does not require quotation marks, but it still requires attribution if it presents someone else's ideas, data, or conclusions. The mere change of sentence order does not make the text an independent study.
Common knowledge does not always require a footnote, but the limit depends on the field and context. Detailed values, definitions, classifications and test results should be sourced. In case of doubt, it is safer to verify the record with the supervisor or according to the university guidelines.
What not to do after seeing a high score?
You should not accidentally replace words with synonyms or break up valid terms just to change the percentage. Such an operation may deteriorate the language, distort the meaning and do not solve the problem of the lack of a source. The goal is the accuracy of the text, not to deceive the comparison mechanism.
It is also risky to upload all your unpublished work to random websites. Before transferring a document to an external entity, you must check the rules of confidentiality, file processing and deletion. The official report and the promoter's comments remain the basis for further actions.
How to prepare for an interview with the promoter?
It is worth making a short list of problematic places: page number, type of similarity, indicated source and proposed method of improvement. Such a table facilitates a substantive conversation and shows that the author is analyzing the report, instead of focusing only on the percentage.
If changes are necessary, work from a copy of the file and retain the version submitted for testing. After corrections, you need to check the footnotes, bibliography and consistency of terms again. The re-examination is decided by the university's procedure, so it is not worth setting it up without consultation.
Start with the specific passage rather than the indicator alone
A similarity report is a starting point for text analysis. For a highlighted passage, check the comparison source, the length of the similarity and how the material is used in the thesis. It matters whether it is a quotation, paraphrase, standard name or extensive borrowing. A percentage alone does not answer these questions. Assessment requires context and the university's procedure, so a colour or single number should not be interpreted mechanically.
Prepare a list of places needing review instead of revising from the first highlight to the last without a plan. Separate correctly marked quotations from passages with unclear references and content that reproduces a source too closely. This distinction helps identify the appropriate action. Not every similarity requires rewriting a sentence, but every problematic borrowing needs an honest resolution. The aim is a properly prepared thesis, not merely a different report result.
Why short and long similarities need different consideration
A short match may concern an institution's name, a term or a conventional phrase. A longer sequence of similar sentences may require closer comparison of the argument and references. Length alone does not settle the issue: a correctly marked quotation can also be long, while a short passage may contain an important idea belonging to someone else. Check the content, attribution and role of the passage in the author's argument together.
Teaching example: a definition quoted verbatim with appropriate attribution requires a different assessment from several paragraphs copied from a source without clearly identifying the extent of borrowing. Do not remove a reference to make the text appear more independent. If a quotation is excessive, you can replace it with a genuine synthesis while still citing the source. The change should result from a better understanding of the literature rather than mechanical word substitution.
Keep a revision table after analysing the report
In a working table, record the location in the thesis, the similarity source, the identified problem and the planned correction. Add a status and note whether a supervisor's decision is needed. For a missing reference, check the content's actual origin. For an unclear paraphrase, compare it with the original. For an overly extensive quotation, consider its function and whether it can be shortened without changing its meaning. Each type of problem requires a different action.
Keep a document version from before the correction and do not mix reports concerning different files. If you changed chapter numbering, record this in the log so the passage can be found later. After revisions, also check the bibliography and neighbouring sentences. Removing one paragraph may break the argument's continuity, and changing a source may require another reference to be updated. Checking similarities should form part of editing the whole thesis.
What the report cannot determine on its own
The report does not replace assessment of argument quality, data accuracy or whether cited findings correspond to the originals. A text may show little similarity yet contain nonexistent sources or incorrect interpretation. It may also contain numerous properly marked quotations whose proportion needs assessment. A low indicator should therefore not be presented as a guarantee of complete independent authorship or high academic quality.
Do not assume one acceptable threshold for all universities and thesis types. Check the procedure in your own institution's current rules. If in doubt, ask for clarification of a particular passage and the expected correction. A discussion based on the text is more useful than asking only for a safe percentage. Do not buy a promise of a guaranteed JSA result as a substitute for preparing the thesis responsibly.
Improve the content instead of circumventing analysis
Do not replace letters with similar-looking characters, insert hidden spaces, turn text into images or use other measures that obstruct analysis. They do not resolve authorship problems and may make the document less readable. If a passage needs independent treatment, return to the sources, identify the main idea and write your own synthesis. Retain a reference to the idea used. Properly documented use of literature is a normal part of academic work.
Before resubmitting the document, compare it with the revision log. Check that the problem has been resolved rather than merely reworded. The author should understand every passage and be able to explain its connection to the topic. Final actions in the system and approval of the report belong to authorised people under the university's procedure. Editorial support can help organise the text but should not promise to replace this assessment.
Summary
The JSA report should be read from the marked passages to their sources, not from one number to a hasty conclusion. A correctly described quotation, title of a legal act and unmarked borrowing may increase similarity, but require a different assessment. The most important thing is to determine whether the author clearly separated his own argument from the content from the sources and whether he applied the principles of his university.
Frequently asked questions
How much percentage in JSA is allowed?
There is no one universal threshold applicable to all universities and all jobs. Detailed procedures are specified in the regulations of the units, and the result requires the supervisor's assessment.
Does a high ratio mean plagiarism?
Not automatically. It may result from, among other things, quotations, names of legal acts, terminology or similarities requiring explanation. You need to analyze the marked places.
What does a low similarity score in a JSA report mean?
A low similarity score does not by itself guarantee that a paper is correct, just as a higher score does not automatically prove plagiarism. The supervisor assesses the specific passages, their sources, the citation method and compliance with the university procedure.
Is it possible to check the work at JSA yourself?
The official examination takes place in accordance with the university's procedure. External services should not be considered a guarantee of an identical result or a substitute for an official report.
Can a similarity result be assessed without reading the thesis?
Source use cannot be assessed reliably from the indicator alone. You need the highlighted passages, their sources and the way they are attributed in the document. Interpret the report in the context of the thesis and the university's current rules.
